[CA] [CA11] AXIOM MFDs and AIS added to Raymarine 2002 sytems

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tom,

System limitations:
- AIS data will not be shared between the Axiom MFD and the devices on the SeaTalk bus (i.e. RL70C, RC530, etc.).
- It has been our experience that the hsb/hsb2/SL Pathfinder Series MFDs will have issues in commanding / cancelling navigation (i.e. Go To Waypoint/Cursor or Follow Route) in such blended systems feature hsb/hsb2/SL Pathfinder Series Displays when interfaced via a SeaTalk to SeaTalkng Converter to a MFD running LightHouse II or LightHouse 3 software. You may want to consider interfacing the Axiom MFD to the older equipment via a NMEA 0183 to SeaTalkng / NMEA 2000 data bridging device (ex. Actisense NGW-1-ISO-STNG, etc.). In doing so, the SeaTalk to SeaTalkng Converter shown within your system would be replaced with a simple powered and properly terminated SeaTalkng / NMEA 2000 backbone. The NMEA 0183 to SeaTalkng / NMEA 2000 data bridging device would then be installed between the NMEA 0183 communications interface of one of the hsb/hsb2/SL Pathfinder Series Displays and the simple SeaTalkng / NMEA 2000 backbone.

Q1 Do I need to power the new SeaTalkNG network?
A1. Yes. See the Limitations listed above.

Q2. Is it OK to have both resistors in the Converter due that I don't have a backbone or should I move one resistor closer to the Axiom 9 with a backbone and a Tee-connector?
A2. Two Termination Plugs must be present in the backbone. In this case, the SeaTalk to SeaTalkng Converter Kit should be replaced with a SeaTalkng 5-Way Connector (part of the simple backbone).

Q3. Is there too many devices on the SeaTalk 1 network, if so, should I have two converters?
A3. N/A ... see the Limitations specified above.
